For example, cystic fibrosis (CF, MIM #219700), neurofibromatosis (NF1, MIM #162200), Charcot-Marie-Tooth neuropathy type 2A (CMT2A, MIM #118210), glycogen storage disease 2 (GSD2, MIM #23200), Huntington disease (HD, MIM #143100), and Duchenne muscular dystrophy (DMD, MIM #310200) are caused by INDELs in the coding regions of DNA. This evidence concerns the gene NF1 and Huntington disease.
